CHECK-ROW ATTACHMENT FOR CORN-PLANTERS.

SPECIFICATION formingpart of Letters Patent No. 689,750, dated December 24, 1901.

Application filed May 3, 1901. Serial No. 58,604. (No model.)

T0 at whom it may concern:

Be it known that I, ELVIS C. ROBERTS, a citizen of the United States, residing at Holdenville, Creek Nation,Indian-Territory, have made a new and useful Improvement in Check-Row Attachments for Corn-Planters, of which the following is a specification.

My invention is an improvement in that class of attachments for check-row corn-- Figure 1 exhibits a perspective View of my improved machine,and Fig. 2 a detail perspective of gearing.

A rectangular frame A is provided with a rigid tongue B and supported at its rear end upon the axle O by transporting-wheels D. Upon the said frame A are fixed two pairs of vertical guides E on opposite sides, between which the shaft F of the marker-wheels G passes. The said shaft passes also through blocks H, which are provided with flanges and adapted to slide vertically between the standards E. It will be seen that by this construction and arrangement the markerwheels G are adapted to work entirely independently of the transporting-wheels D and to rise and fall vertically according to the inequalities of the surface over which the machine passes. The wheels G are provided on their peripheries with small cross-pieces g for making depressions in the surface in the usual way.

Upon the central portion of the shaft F is mounted a crown-wheel I, whose teeth mesh with the lantern-pinion J, arranged vertically and journaled at the rear end of the tongue B. The upper end of said lantern-pinion J is provided with a pivoted slotted guide K, arranged vertically and pivoted thereto, so that the pinion is adapted to rotate independently. The shaft F passes through the slot in said guide K, and a collar K is provided, as shown, for holding the guide in due position while sliding vertically corresponding to the movement of the shaft F. The lower portion of the lantern-pinion J is provided with a cam or wiper L, which projects laterally and is adapted to engage the teeth of the star or tappet wheel M, keyed upon the shaft N, which operates the seed-dischargers 0, located in the seedboxes P. The latter are located directly under the shaft F. The seed-dischargers may be in the form of perforated disks arranged in the bottom of the. seedbox P and provided underneath with bevel-gears, (not shown,) which may engage corresponding gears on the shaft N.

It is apparent from this construction and arrangement of parts that as the markerwheels rotate their shaft F, carrying the crown-wheel I with it, will impart rotation to the lantern-pinion J and that the cam L of the latter will in turn rotate the tappet-wheelM intermittently, and thus cause intermittent rotation of the seed-dischargers O and a consequent intermittent dropping of the corn or other seed.- In case it should be desired to discharge seed at a faster rate, two or more cams L may be attached to the lantern-pinion J, and for this purpose the face of said pinion is provided with a series of holes to receive the cams.

It is apparent that the described arrangement and operation of the crown-wheel with the pinion J remains the same whatever he the vertical adjustment of the shaft F, since the pinion is elongated to the degree required for this purpose.

The seed discharges through tubes formed in the rear part of the furrow-openers.

What I claim is- The combination with the main frame having rear transporting-wheels, furrow-openers and vertical guides at the front as described, of the marker-wheels and their axle which is adapted to play vertically between the said guides, a toothed wheel fixed on the axle, and the elongated lantern-wheel J, pivoted at its lower end and having at its upper end the vertically-slotted guide K which receives the axle and allows the same to play vertically, the seed-dischargers and shaft geared therewith, a tappet-wheel fixed on said shaft, and a cam or wiper fixed on the lower portion of the aforesaid lantern-wheel and adapted to engage the tappet, all arranged and operating, substantially as shown and described.

ELVIS O. ROBERTS.
